U.S. Secretary of State Rex Tillerson arrived here Friday morning for the second stop of his East Asian tour to talk with his South Korean counterpart over the Korean Peninsula nuclear issue.

The airplane carrying the top U.S. diplomat arrived in the Osan air base, some 60 km south of the capital city Seoul, at about 10:10 a.m. local time, TV footage showed.

Tillerson visited Japan on Thursday, meeting Japanese Prime Minister Shinzo Abe and Foreign Minister Fumio Kishida. He is scheduled to leave for Beijing on Saturday.

Tillerson is scheduled to meet South Korean Prime Minister Hwang Kyo-ahn, who is serving as acting president as former President Park Geun-hye has been ousted through impeachment.

After the meeting, he will hold a joint press conference with his South Korean counterpart Yun Byung-se in Seoul.

Key agenda on the table for Friday's talks between Yun and Tillerson would be the Korean Peninsula nuclear issue.

Tillerson said in Tokyo Thursday that diplomatic and other efforts of the past 20 years to realize the denuclearization of the peninsula have failed, stressing the need for a new approach to the issue.
